"U.S. environmental regulators said testing on higher ethanol blends in motor fuels will not be finished until September, a delay ethanol groups said would hurt jobs and worsen a supply glut.

The Environmental Protection Agency told Reuters that tests on boosting the blend rate of gasoline to 15 percent ethanol, or E15, on new vehicles built after 2007 would not be completed until the end of September.

Originally the EPA said testing on E15 on cars as old as 2001 models would be finished by mid-year."
